As an example cut 0 is activated and the according attachments are made to matrix 1, projection 2, spectrum 3 and directory 4.
tv cut activate 0
tv cut attach matrix 1
tv cut matrix attach-projection 2
tv cut attach spectrum 3
tv cut attach directory 4
Now change to a suitable directory and open the matrix as well as the directory and load the projection.
tv cd /matrix1
tv cut directory open 4 /220Th/220Th.cutdir
tv cut matrix open /220Th/220Th.mtx
tv spectrum read /220Th/220Th.pry 2
Examples for the comparison of matrices, where attachments for several matrices are made, are given in chapter 5.6.
